Abstract

A rubber track has lugs (12A, 12B) formed on its outer peripheral surface in two rows of a first row and a second row that are arranged with the same pitch in the circumferential direction, and the rubber track also has guide juts formed on its inner peripheral surface at the equal intervals. Ends (13A, 13B), located in the center part in the lateral direction of the track, of the lugs (12A, 12B) are superposed on a projection area of a guide jut (16). Because the ends (13A, 13B) are superposed on the projection area of the guide jut (16) having high rigidity, the ends bend less than other portions when the track is wrapped around a sprocket etc. This prevents concentration of strain at the ends (13A, 13B), and as a result, cracks in the ends (13A, 13B) of the lugs (12A, 12B) are prevented.
